	== ~~Structure~~ ==		==Anatomy==

			The primary function of the lacrimal hamulus is to provide structural support to the [[lacrimal apparatus]], particularly the [[lacrimal sac]], which is essential for the proper drainage of [[tears]] from the [[eye]] into the [[nasal cavity]].

	== ~~Function~~ ==		==Clinical significance==
			In some cases, the lacrimal hamulus can be involved in [[nasolacrimal duct obstruction]], which can lead to [[epiphora]] (excessive tearing) or [[dacryocystitis]] (inflammation of the lacrimal sac). Surgical procedures involving the [[lacrimal system]], such as [[dacryocystorhinostomy]], may require careful consideration of the lacrimal hamulus.
	~~The primary function of the Lacrimal Hamulus is to serve as a turning point for~~ the [[~~Tendon~~]] ~~of the~~ [[~~Tensor Tarsi Muscle~~]]~~.

	~~== Clinical significance ==~~

	~~Due to its small size and delicate structure~~, ~~the Lacrimal Hamulus is susceptible to fractures. Fractures of the Lacrimal Hamulus can lead to~~ [[~~Dacryocystitis~~]], ~~which is an inflammation~~ of the ~~[[Lacrimal sac]] due to obstruction of the [[Nasolacrimal duct]]~~.

== Lacrimal Hamulus ==

The '''Lacrimal Hamulus''' (''Hamulus lacrimalis'') is a small hook-like structure in the human skull. It is a part of the [[Lacrimal bone]], which is one of the smallest and most fragile bones of the face. The Lacrimal Hamulus is located at the medial wall of the [[Orbit (anatomy)|orbit]], where it serves as a turning point for the [[Tendon]] of the [[Tensor Tarsi Muscle]].

[[File:Lacrimal bone - close-up - anterior view.png|thumb|right|200px|The Lacrimal bone of the human skull, showing the location of the Lacrimal Hamulus (highlighted).]]

== Structure ==

The Lacrimal Hamulus is a small, hook-like projection that extends from the lower part of the [[Lacrimal bone]]. It is located at the front part of the [[Medial wall of the orbit|medial wall]] of the [[Orbit (anatomy)|orbit]], near the [[Lacrimal sac]]. The Lacrimal Hamulus is directed horizontally and slightly backwards.

== Function ==

The primary function of the Lacrimal Hamulus is to serve as a turning point for the [[Tendon]] of the [[Tensor Tarsi Muscle]]. This muscle is responsible for the tension of the [[Tarsi (eyelid)|tarsi]] and the opening of the [[Lacrimal canaliculi]], which are small channels that drain tears from the [[Eye]] to the [[Nasal cavity]].

== Clinical significance ==

Due to its small size and delicate structure, the Lacrimal Hamulus is susceptible to fractures. Fractures of the Lacrimal Hamulus can lead to [[Dacryocystitis]], which is an inflammation of the [[Lacrimal sac]] due to obstruction of the [[Nasolacrimal duct]].
